Plush Interior Padding 

Full-face helmets are often restrictive, prompting most riders to worry about their comfort.

Enhanced Safety Attributes

Underneath the fiberglass shell, an EPS liner is a MIPS slip-plane that enhances safety against brain injuries from sudden rotational forces. Here, in the event of a collision that prompts the head to spin, the MIPS layer slows down the brain matter from moving. That way, there is minimal brain damage minimizing fatalities. 

Next, there are emergency release cheek pads that come in handy in the event of a crash. Here, instead of yanking the helmet off the injured rider, exposing him to additional spinal injury, you gently remove the cheek pads to loosen the helmet’s grip around the head. 

Ample Channeled Ventilation

There are 14 vents at various strategic points, including the brow line of the Giro Disciple MIPS. These holes provide internal channeling of fresh air into and out of the helmet, keeping the rider refreshed regardless of the weather elements.

Secure D-Ring Buckle System

This helmet uses the comfortable D-Ring Buckle system that is not too tight. Instead, these tried-and-true fasteners won’t break, allow for infinite adjustments, and resist pulling once you lock them in place.

  1. A great helmet when riding in the mountains is very needed. You have written excellent reviews on some great-looking helmets. I will be able to make an informed choice about the one that will suit me the best. This piece of equipment is absolutely essential when on trials in the backcountry. My daughter enjoys mountain biking. One day she was out racing on the mountain when she came around a sharp corner and came face to face with a bear. Instead of running into the bear, she veered the bike off the trail and went down a steep incline of at least 15 feet. I thank God to this day that she was wearing a protective helmet!
